I made this using Stella 4d: Polyhedron Navigator, available at http://www.software3d.com/Stella.php.
This compound was created using Stella 4d, software you can try here.

This is my tattoo of pi, my favorite number. The circle which surrounds pi does not close because it is only three times as long as the diameter of the circle, in “deference” to the infamous “pi is exactly 3” verse of the Bible (I Kings 7:23).
